Protection circuits
The MC 15 speaker has several built in protection circuits to reduce the
risk of hazard or damage due to overloading.
The internal power amplifiers have thermal protection. This activates if
a problem should occur, and helps protect both the electronics and the
loudspeaker drivers.
There is also a thermal sensor measuring the temperature on the heat
sink
(5)
. An electronic circuit will mute the signal when too high
temperature is reached. The Protection LED
(11)
on the front will light
up when this happens.
There is an overload protection circuit on the tweeter to prevent burning
the tweeter driver in case of overloading. This circuit will mute the
tweeter signal if too much current is fed to the tweeter.
The woofer channel has a built in limiter that protects the woofer unit
from too much excursion. It works by reducing the gain of the circuit
when a certain threshold level is reached.
NOTICE:
Avoid running the system into severe clipping. Despite the
advanced protection system, you may still be able to
damage your speakers by severe overpowering. The limiter
works over a certain range, but exceeding this level may
send a severely clipped signal to your drivers. When a
noticeable distortion occurs, please turn down the level to
your speakers.
